About

Jade Multiply

With Jade Multiply you will master your times tables quickly. It remembers the questions you get right and wrong, and asks you the ones that you most need help with. It also will review questions with you at gradually increasing intervals (a technique known as spaced repetition) so you never forget. We designed and built it for our kids, and hope that many others will use it. It is ad-free, and will remain so. We are just getting started, and have many new features planned. Please let us know what would be useful to your family, school, or homeschool group.
